Hierarchical Routing Protocol for Free-Space Optical Mobile Ad hoc Networks (FSO/RF MANET)

چکیده
The existing routing protocols in mobile ad hoc network such as DSDV, AODV, DSR, ZRP, SRL, HSR, etc cannot be utilized for FSO/RF MANET owing to certain disjoint characteristics of free space optical (FSO) and MANET. The characteristics include accommodating directionality, accuracy in routing information, memory, reduced overhead and delay. In this paper, a hierarchical routing protocol for FSO/RF MANET is proposed. In this protocol, a network connector which connects the hybrid networks is defined. The cluster formation is based on Neighborhood Discovery Algorithm. In each cluster, the node, which is nearer to the network connector, is elected as cluster head. Each network connector gathers information of all cluster members and their CH and builds a routing table using network connector discovery algorithm. When the source node of a network wants to send data to destination node in another network, FSO/RF MANET routing protocol is used. Simulation result, show that the proposed routing protocol minimizes the delay while enhancing the end-to-end throughput.

In this paper, we introduce a hybrid free-space optics/radio frequency (FSO/RF) networking paradigm for mobile robot teams. We believe that such a model will emerge as a consequence of inherent limitations of RF based approaches. FSO technology has the potential to provide tremendous increases in per-node throughput for a mobile ad-hoc network (MANET). To motivate this paradigm, we first provid...
